GEORGE C. FRAZIER, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO NATIONAL GASKET COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA..

BOX-LID FASTENER.

To all whom t may concern:

Be it known that I, GEORGE C. FRAZIER, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Box-Lid Fastener, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view of a portion of a box and its lid or cover, and showing my invention applied thereto, Fig. 2 is a sectional view of the same 5 Fig. 3 is a perspective view of one of the fasteners removed and Fig. 4 is a view similar to Fig. 2 but showing a slightly modified form of the fastener.

My invention has relation to box lid fasteners, and is designed to provide a simple, convenient and efficient fastener by means of which the lid or cover of a box may be temporarily or permanently secured. in place.

The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction without departing from my invention as defined in the appended claims.

In the drawings, the numeral 2 designates the body portion of the box, and 3 the lid or cover. One member of each fastening is secured to the body portion 2, andconsists ofa strap or clip having a lower portion 4, which is perforated to receive fastening nails 5, and an upper outwardly offset portion 6 formed with a slot 7 having an inwardly extending portion S into which the slot 7 is extended. The other member of each fastening consists of an ordinary headed bolt 9, which is inserted upwardly through the slot 7 before the other member of the fastening is applied to the box, and which is arranged to be moved into a slot 10 in the projecting or overhanging edge of the lid or cover 3, The bolt 9 is secured by a nut 11, preferably a wing nut, which is screwed down against a bearing plate 12 fastened to the lid or cover, and having its outer edge portion turned upwardly as shown at 13 whereby when the nut is screwed tightly down this turned-up edge portion of the plate 12 will act as a lock for the nut to prevent the bolt being disengaged from the slot 10.

In the modification shown in Fig. 4, the construction is the same as that shown in the Specification of Letters Patent.

Serial No. 430,527.

other iigures except that the member of the fastening which is secured to the body of the box has a member 14 which forms a continuation of the inwardly turned portion 8, and which is bent downwardly against the inner side of the member L1, forming a double thickness of metal through which the securing nails 5 pass. This form of clip is somewhat stiffer and stronger than that shown in Figs. 1, 2 and 3. It will be seen that the headed portion of the bolt forms a swivel connection with the slotted clip or strap which is secured to the body of the box, so that the bolt may be readily swung into and out of engagement with the slot in the edge of the cover, while the head of the bolt will prevent the separation of the two members of the fastening after the fastening has once been applied to the box. The entire device can be constructed at a very low cost. The member of the fastening which is secured to the body of the box can be readily formed or stamped from sheet metal, and an ordinary bolt can be used for the other member of the fastening. When the nuts 11 are firmly screwed down, the cover or lid will be securely held in place. Any desired number of fastenings may of course be applied to the box on two or more sides thereof.

I claim:

1. A box fastener comprising an offset slotted clip or plate, means for securing said clip to the body of a box, a headed bolt passing through the slot of the clip, the head of the bolt engaging the walls of the slot, a nut on said bolt, and a slotted bearing plate adapted to be secured to the box cover and having a projection for engagement with said nut; substantially as described.

2. The combination with a box having a cover with an overhanging slotted edge, of a fastening device for the cover, consisting of a slotted offset member, a headed bolt passing loosely through the slot and bodily movable therein, the head engaging the walls of the slot, a nut for engaging the bolt, and a bearing and locking plate on the box cover for the nut, substantially as described.

3, In a box fastening, the combination with a cover having an overhanging slotted edge, of a clip secured to the body of the box, and having a vertically slotted portion which is bent upwardly and outwardly away from the box, and then inwardly toward the box,

the slot therein extending through the up- Wardly and' outwardly bent portion and into the inwardly extending portion, and a heeded bolt inserted loosely through said slot with its head Within the bent portion of the clip7 and a nut on the free end of said bolt, substantially as described.

In testimony whereof, I have hereunto setl my hand.
